This is a difficult one to advise anyone about and I think Rork has given a lot of sensible advice. I know what those comfort zones feel like, so don't let that be the main reason for any decision you make, particularly if you have a route back to it later if things don't work out. I would certainly go to the next stage and find out more from this woman and then write down the pros and cons, as Rork suggests. You obviously find the option attractive, or you wouldn't be thinking about it. In that situation I would ask myself whether it is my heart or my ego that is making it attractive. You must obviously be flattered by the fact that someone recognises your talent. If I was sure it was my heart that was taking me down that route and I was still tempted to say 'no', then I would think very seriously if that would be a decision I would regret later in life... not easy I know :) but sometimes it is easier to go back than to regain a lost opportunity. I don't know if any of this helps... I hope it does, but, whichever way you go, you have my best wishes.
